The controllable vector jet propeller comprises a water pump, a control assembly and a Tesla valve device, the water pump is used for forming jet flow with pressure, and when thrust of the controllable vector jet propeller needs to face one of the upper direction, the lower direction, the left direction and the right direction, the Tesla valve device is connected with the control assembly. If yes, the outer barrel is controlled to open a first opening in the direction, the jet flow forms wall-attached jet flow on the opposite side of the first opening, and then the wall-attached jet flow is guided into a corresponding Tesla valve channel and is transmitted forwards in a one-way mode; when the pushing force needs to be made to face the right front, the outer barrel is controlled to close all the first openings, and jet flow is directly guided into the straight channel from the main channel to form forward pushing power; the controllable vector jet propeller designed based on the Coanda effect and the Tesla valve has the advantages of being simple in structure, convenient to control, stable in jet flow and high in energy efficiency, installation is convenient, meanwhile, no external complex auxiliary mechanical structure exists, and electromechanical design is facilitated.
本发明公开了一种可控矢量射流推进器及水下机器人,可控矢量射流推进器包括水泵、控制组件及特斯拉阀器件,水泵用于形成具有压力的射流,当需要使可控矢量射流推进器的推力朝向上、下、左、右的其中一个方向时,则控制外筒将位于该方向的第一开口打开,射流在第一开口的对侧形成附壁射流,并随之导入至对应的特斯拉阀通道,以单向的形式向前传输;当需要使推力朝向正前方时,则控制外筒关闭所有第一开口,射流从主通道直接导入至直通道,形成向前推动的动力;基于康达效应及特斯拉阀设计的可控矢量射流推进器具有结构简单、控制方便、射流稳定以及能量效率高的优点,安装方便的同时没有外部复杂的辅助机械结构,便于机电设计。
